show you what’s involved
prove that yes, these boards really do go together
remind you that I sell the boards
and save you the headache if you’d rather not do the soldering yourself
If you watch this and think:
“Yeah… I’m not doing that.”
Good news — I’m now offering a soldering service on the website.
For $25, I’ll solder and test up to 4 boards for you.
If you need more than 4, just stack the service.
That means:
no solder station setup
no chasing tiny parts around the desk
no wondering if you bridged something
no guessing if it works
You get the board, I do the bench work.
Check the website for:
AIOC boards
DI boards
New soldering service
If you want the fun of building it yourself, this video should help.
If you want the result without the tiny electronics adventure, I’ve got you covered.

Today I decided to try something a little different – AM on the UK 60 metre band.
A few of us had been chatting on 40m during the week and it got me wondering how AM would sound on 5 MHz. The result surprised me!
In this video I show:
• How I set up AM on the Kenwood TS-990S
• Why carrier power matters
• Why I turn the speech processor OFF
• How to achieve approximately 100% modulation
• A real off-air recording from the Hack Green SDR
My AM Setup Checklist:
✓ AM mode selected
✓ Speech Processor OFF
✓ Compression OFF
✓ TX Bandwidth = 100 Hz – 4 kHz (or widest available)
✓ Carrier adjusted so ALC is at or near ZERO
✓ Mic Gain adjusted for voice peaks approximately 4× carrier power
✓ Monitor audio sounds clean and natural
Example:
Carrier = 25W
Voice Peaks ≈ 100W
This gives approximately 100% modulation.
If you’re active on AM, let me know your favourite setup, microphone and operating frequency in the comments below.
Note: On AM, the audio appears on both sides of the carrier. So a 4 kHz audio bandwidth results in an RF signal approximately 8 kHz wide. If that seems a bit generous, try 100 Hz – 3 kHz instead. It’ll still sound great and occupy roughly 6 kHz of bandwidth.
Flash Meshtastic and Make First Contact: Meshnology N39 Build
In this video, I build an N39 Meshtastic node kit, flash the latest Meshtastic firmware, pair it to the Meshtastic app, and test basic communication with another node.

If you are wondering how to build a Meshtastic node from a kit, how to flash Meshtastic firmware, or how to get your first Meshtastic message sent between two LoRa nodes, this video walks through the full process from start to finish.
Meshtastic is an open-source, off-grid mesh communication system that uses LoRa radios to send text messages and position data without relying on cell service, Wi-Fi, or internet. A Meshtastic node can be used for hiking, camping, emergency communications, neighborhood mesh experiments, ham radio-adjacent learning, or just exploring what LoRa can do.
This build uses the N39 Meshtastic kit. The goal is to go from parts in a box to a working Meshtastic node that can talk to another node.
In this video:
– What comes in the N39 Meshtastic kit
– How the N39 hardware goes together
– How to flash Meshtastic firmware
– How to use the Meshtastic web flasher
– How to connect the node to the Meshtastic app
– How to pair the node with a phone
– How to send a test message
– How to confirm the node is working
– Common build and flashing issues to watch for
This is intended as a beginner-friendly Meshtastic build guide. You do not need to be a radio expert to follow along, but you should be comfortable handling small electronics, USB cables, firmware flashing tools, and basic troubleshooting.
Meshtastic works by creating a mesh network between compatible LoRa nodes. Each node can pass messages along to other nodes, extending communication beyond direct radio range when enough nodes are present. Range depends on antenna choice, terrain, height, power settings, and local RF conditions.
If your Meshtastic node will not flash, will not pair, or will not send messages, check the USB cable, serial driver, boot/reset button timing, firmware target, Bluetooth pairing state, and app settings. Most Meshtastic setup problems are small cable, driver, firmware, or pairing issues rather than a failed device.
This video is part of my Meshtastic playlist where I build, test, flash, compare, and troubleshoot different Meshtastic nodes and LoRa devices.

How To Setup Your QMX With Winlink Express & VARA HF
I had all but given up on this a while ago but a viewer sent me a Winlink email asking about setting up the QMX with Winlink Express. I didn’t think it was possible but I asked in the chat of @HamRadioCrashCourse live stream on Saturday if it was possible and the answer was YES. So after some tinkering around with settings and some research on the https://groups.io/g/QRPLabs/topic/qmx_ssb_settings_for_winlink/111820559 forum I was able to get it to work. Huzzah! A little niche but for those of us with a QMX (I now have 2 but I need to build the second one) who want to be able to send emails over HF, this is how to do it.
I’m also running Windows on my Mac for this. If you missed the video on how to setup UTM and instal Windows and Winlink Express on your Mac, for FREE here’s the link: https://youtu.be/7jtth4dylBI
